We present an upgraded setup for cooling and trapping of ytterbium atoms in a optical clock experiment. The experiment aims to cool and trap ytterbium atoms in a two stage magneto-optical trap (MOT) (at 399nm and 556nm for the first and second stage, respectively) and to probe the narrow-line clock transition at 578 nm in an optical lattice at the magic wavelength (759 nm). We describe here the generation of all the laser sources and the design of a new physic package, including the vacuum chamber and the atomic source.
